ORUNE_LOC_SERI Wastewater Treatment Plant, Orune, Sardinia, Italy

ORUNE_LOC_SERI is a municipal wastewater treatment plant located in Orune, a town in the province of Nuoro, Sardinia, Italy. The plant serves a population of approximately 3,021 residents and is part of the region's wastewater infrastructure for inland communities. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 3,100 cubic meters per day and a discharge volume of 598.05 cubic meters per day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Tyrrhenian Sea via small rivers and streams in the region. The plant plays a key role in protecting the local environment by reducing organic pollutants and nutrients before discharge, supporting the ecological health of Sardinia's inland and coastal waters.

The plant discharges into the local watershed of the Cedrino River basin, which flows into the Tyrrhenian Sea near the Gulf of Orosei. This coastal area supports diverse marine life and is an important ecological zone for Sardinia. The secondary treatment helps reduce nutrient loads, protecting downstream water quality and the sensitive coastal ecosystem.
